#12706: Collecting type info is slow -------------------------------------+------------------------------------- Reporter: vshabanov | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by nomeata):
Is it expected behavior and some performance improvements are planned or it's a bug?
I would not be surprised to find that this is a rather rarely used feature and may not have gotten the necessary attention. But this might also mean that there is some low-hanging fruit. I would recommend building a profiled compiler and get a profile for this bit, just to see if there are obvious hotspots. vshabanov, are you interested in working on this, or just reporting it for now? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12706#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
